Niagara Dynamic Input Script - Namespace Error when using "Map Get" + "Particles.Something"

[sunwolz]

Hello. I’m a newbie at Niagara.
I get the following error when trying to Compile a custom Niagara Dynamic Input Script. The “Map Get” function when set to get Particle.Velocity (and probably some other particle stuff aswell) triggers this error.
As far as I can tell, the script seems to WORK either way, but having the error makes me uncomfortable. Any info on the topic would be appriciated.

Variable Particles.Velocity is in a namespace that isn’t valid for reading. Enable at least one of the ‘particle’ options in the target usage bitmask of your script to access the ‘Particles.’ namespace. - Node: Map Get -
Error compiling input for convert node. - Node: Break Vector Pin: Input 1 -

Were you ever able to figure this one out? I ran into the same thing.

Me too, haven’t figured out

How are your Script Details panel > Script > Module Usage Bitmask flags set? The error message suggest that none of the “Particle …” is enabled.
